The
main task at designing of measuring instruments, sensors and transducers was
and is at present to reach high metrology performances. At different stages of
measurement technology development, this problem was solved by different ways.
It is technological methods, consisting in technology perfection, as well as
structural and structural - algorithmic methods. Historically, technological
methods have received prevalence in the USA, Japan and Western Europe
countries. The structural and structural-algorithmic methods have received a
broad development in the former USSR and continue the developing in NIS
countries. The improvement of metrology performances and extension of
functional capabilities are reached by implementation of particular structures
retrieved in most cases by heuristic way in combination with calculations and
signal processing.

In this section of IFSA Web site the references from the journal
"Measuring Instruments and Control Systems" (1967 - 1991),
concerning frequency sensors and transducers are collected. The journal was
publishing in the former USSR and devoted to research and development of
methods of measurements, sensors, instrumentation and sensor applications in
control systems. This reference list testifies about intensive researches in
the field of frequency sensors and transducers carry out in USSR. As far back
as 1961 professor P.V. Novitskiy has written: "...In the prospect, it is possible to expect, that class of
frequency sensors will be received such development, that the number of known
now frequency sensors will exceed the number of known now amplitude sensors...
". Although today there are frequency sensors practically for any
quantities, this prognosis was not justified in the full because of objective
reasons: beginning of "perestroika”,collapse of Soviet economy and science. Today situation gradually
varies to the best and, despite of the lost years, it is possible to forecast,
that the frequency and digital sensors will occupy a leading position all over
the world in the Next Millennium.

The
knowing with these articles will allow speeding up advance in development of
new sensor principles and successful combination of technological, structural
and structural-algorithmic methods of metrology performances improvement of
sensors.

In
spite of the fact that the journal " Measuring Instruments and Control
Systems " was published in Russian language, you can order translations
of required articles in English. The price is from 10 up to 30 $ USA depending
on the article size.
